The three main pressures that determine glomerular filtration are 1) glomerular hydrostatic pressure, which promotes filtration by pushing fluid and solute out of the blood into the filtrate, 2) capsular hydrostatic pressure, which opposes filtration by pushing back against the fluid in the Bowman's capsule, and 4) blood colloid osmotic pressure, which also opposes filtration by pulling water back into the capillaries due to the presence of proteins in the blood.
